Help:Internal links

So there's an entry in Wiktionary, say pet, and you want to add, to that page, a link to another entry (which already exists, or should), but don't quite know where to put the link. This page will help you decide that. We'll continue using pet as our example throughout.

If the word you're adding is so similar that people are likely to look it up instead of pet — or vice versa — then you should use {{also}} right at the top of the page. This applies especially to terms that differ only in spacing, punctuation, capitalization, or diacritics form the present word, and even applies to words in other languages; so in our case it would apply to Pet., PET, and pět, and you'd put {{also|Pet.|PET|pět}} atop the page; that will yield

Well, the example "pet" fails here, unfortunately; let's use another. The term Jack O'Lantern is defined as Alternative spelling of jack-o'-lantern, so doesn't need any other link to the page jack-o'-lantern. But the latter needs a link to the page Jack O'Lantern. So we put that under an Alternative spellings or Alternative forms header. (You can use "forms" in any event; you can use "spellings" if the only difference is one of spelling.)

The Alternative forms or Alternative spellings header is a level-three header: it should have three equal signs on each side, like this: ===Alternative forms===. It should precede any other level-three header.

If pet is derived from another word (as, in one case, it is, from petition), then a link to the latter word should be in the Etymology section of pet. That's true whether the other word is in the same language as pet or another, and applies even if pet is a loanword.

If other words are derived from pet, then they should be listed under a Derived terms header if they're in the same language, and under Descendants if they're in another. These sections are one header-level lower than the part-of-speech header, so if ===Noun=== has three equal signs, then ====Descendants==== should have four.

Finally, if there are words related etymologically to pet but not in a direct line of derivation above or below it, they can go under a Related terms header, also one header-level lower than the part-of-speech header.

Translations of an English word like pet into other languages go under a Translations header. (We do not include translations of non-English words, except into English.) This should be one header-level header lower than the part-of-speech header, so if ===Noun=== has three equal signs, then ====Translations==== should have four.

They should not also be added as interwiki links [[fi:lemmikkieläin]].
